Ethanol alcohol gas alarm calibration device

Ethanol alcohol gas alarm calibration device(High concentration ethanol alcohol generation device)

Ethanol alcohol gas alarm calibration deviceAccording to the principle of dynamic volume saturation method in GB/T 5275.9-2014, a constant temperature design is adopted to continuously and dynamically generate ethanol gas in the air, with a volume concentration of not less than 2.1%, meeting the requirements of JJG 693-2011 Combustible Gas Detection Alarm Verification Regulations for ethanol alarm lower limits of 60% LEL, 40% LEL, 10% LEL, and concentrations greater than the alarm set point. The device uses liquid ethanol as the raw material to produce ethanol gas in the air, with low operating costs, convenient and fast operation, high work efficiency, and light weight, which can be used for on-site verification/calibration.

Ethanol alcohol gas alarm calibration deviceTechnical Indicators:

The concentration range of ethanol gas that occurs: not less than 2.1%;

The concentration repeatability of the ethanol alcohol alarm calibration device is less than 0.59%;

The injection flow rate is not less than 1L/min, the flow rate is adjustable, and the working voltage of the flow wave during the injection process is AC (22022) V; Movement not exceeding 4%;

Working environment: temperature (15~30) C, relative humidity 20%~85%

Features
